I think you need to read up here and do a search on the forum as there are many posts on building control panels so that you will understand the basics.
.
Things like earthing, grounding with star ppoints etc. be aware that with the transformer that the mounting bolt must ONLY be earthed at one end ie do not connenct any earth to the top end of the bolt (this would create a shorted turn on the transformer).
.
You will need cy 4 core 1mm or 1.5 mm cable for the motors and spindle. (earth the braids at the control box only to a star point).
.
If you put up a circuit diagram people on here will take a look and check it out.
